Summary: | To the Editor: A 60-year-old man was admitted to our emergency department with a new-onset sudden palpitation and precordial discomfort that occurred several times a day. Sustained monomorphic ventricular tachycardia (VT) of a right bundle-branch block (RBBB) pattern (245 beats/rain) was documented, which was reversed into a sinus rhythm after syncbronized cardioversion. Subsequent 12-lead electrocardiogram revealed a normal sinus rhythm with T-wave inversion in leads V4 to V6 and ST segment elevation in leads V 1 to V3 (78 beats/min). He had been diagnosed with diabetes about 10 years ago which was well treated. There was no thmily history ofarrhythmogenic cardiomyopathy or either signs or symptoms of heart disease. Myocardial enzyme levels, including troponin l, creatine kinase isoenzyme MB, and myoglobin, were within normal level. The level of serum C-reactive protein and D-dimer was normal. Transthoracic two-dimensional echocardiography presented a normal left ventricular (LV) global systolic function (an end diastolic/systolic volume of 150/66 ml, an ejection fraction of 57%), an LV pseudoaneurysm (apex, 4.2 cmx 2.6 cm) [Figure 1], and normal morphological right ventricle (RV). Coronary angiography showed normal coronary arteries. |
